Some advantages of Cobalt-tungsten alloy

Cobalt-tungsten alloy is a high-performance hard alloy with super-strong hardness and wear resistance. Hard alloys are mainly used for manufacturing cutting and grinding tools, as well as high-temperature, high-pressure, and high-impact parts for aerospace, defense, petroleum, chemical, nuclear and other industries.

Cobalt-tungsten alloy is composed of two rare and valuable elements, cobalt and tungsten. Tungsten is a metal with the highest melting point and the highest tensile strength, usually used as an alloying element, mixed with other base metals, to improve the performance of the alloy. Cobalt-tungsten alloy usually contains 90-97% of tungsten, the rest is cobalt, and a small amount of other elements, such as titanium, hafnium, chromium, rhenium, etc., to improve the ductility and machinability of the alloy.


Cobalt-tungsten alloy has various density grades, ranging from 16.85 to 19.3 g/cm3, and the tensile strength can reach 1000 MPa. It is silver-gray, smooth, and hard. It has excellent thermal conductivity and electrical conductivity, as well as a low coefficient of expansion. It is also a non-magnetic and non-toxic material, suitable for various application scenarios.

Some advantages of using cobalt-tungsten alloy are:

  • It can resist deformation and fracture under high stress and impact conditions, such as in aerospace, defense, and mining industries.

  • It can withstand high temperature and corrosive environments, such as in petroleum, chemical, and nuclear industries.

  • It can provide effective radiation shielding, because it has 1.7 times the radiation absorption capacity of lead, without the health hazards of lead.

  • It can provide precise balance and vibration control, because it has high density and high elastic modulus, such as in automotive, medical, and sports industries.

  • Cobalt-tungsten alloy has various forms, such as rods, bars, plates, sheets, wires, tubes, and custom shapes. It can be machined, welded, soldered, and coated according to your specifications. It can also be combined with other materials, such as ceramics, polymers, or composites, to produce hybrid products with enhanced performance.
